Apple's annual developer conference in San Francisco.
New iMacs Still Expected to Ship in November-December
9to5Mac now reassures us that Apple's original plans are still intact for the iMac. The new 21.5" iMacs are said to already be shipping to distribution centers, while the 27" iMacs are due in December. Supplies, however, are likely to be very short through the rest of the year.
Apple continues to list November and December availability dates for the new iMacs in their online store. Pre-orders are not yet available but are expected by the end of November.
